Abstract

Un método para renderizar un elemento de audio (por ejemplo, un elemento de audio espacialmente heterogéneo), en donde el elemento de audio tiene una extensión y se representa utilizando un conjunto de altavoces virtuales que comprenden un altavoz virtual intermedio. El método incluye, basándose en la posición de un oyente, seleccionar una posición para el altavoz virtual central y/o calcular un factor de atenuación para el altavoz virtual central.A method of rendering an audio element (e.g., a spatially heterogeneous audio element), wherein the audio element has an extent and is represented using a set of virtual speakers comprising an intermediate virtual speaker. The method includes, based on the position of a listener, selecting a position for the virtual center speaker and/or calculating an attenuation factor for the virtual center speaker.
